# Libraries do not generate the correct ABI code (ChannelState enum causes errors)
# So the Ibc.sol abi generated code from abigen throws errors but is not needed.
# This is because the types exported are included in the ABIs of contracts and
# correctly interpreted (enums -> uint8 etc), the library methods are used inside
# of other contract methods and thus bindings for them do not need to be generated
# as they are not publicly exposed, but rather used within the contract itself.
